Chrysanthemum plant named ‘DLFVIBE2’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘DLFVIBE2’, characterized by its upright plant habit; vigorous growth habit; dark green-colored leaves; uniform and freely flowering habit; strong upright flowering stems with numerous inflorescences; single-type inflorescences with bright yellow-colored ray florets and bright green-colored disc florets; and relative tolerance to high and low production temperatures.

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘DLFVIBE2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum X morifolium,commercially grown as a cut flower and hereinafter referred to by thename ‘DLFVIBE2’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Maasdijk, The Netherlands. The objective ofthe breeding program is to create new freely-flowering cut Chrysanthemumplants with attractive inflorescences, strong flowering stems andexcellent postproduction longevity.

The new Chrysanthemum plant originated from a cross-pollination made bythe Inventor in Maasdijk, The Netherlands on Sep. 12, 2014, of aproprietary selection of Chrysanthemum X morifolium identified as codedesignation DB 11587, not patented, as the female, or seed, parent witha proprietary selection of Chrysanthemum X morifolium identified as codedesignation DB 43868, not patented, as the male, or pollen, parent. Thenew Chrysanthemum plant was discovered and selected by the Inventor as asingle flowering plant from within the progeny of the statedcross-pollination in a controlled greenhouse environment in Maasdijk,The Netherlands on Sep. 4, 2015.

Asexual reproduction of the new Chrysanthemum plant by terminalvegetative cuttings in a controlled greenhouse environment in Maasdijk,The Netherlands since Sep. 4, 2015 has shown that the unique features ofthis new Chrysanthemum plant are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘DLFVIBE2’. These characteristics incombination distinguish ‘DLFVIBE2’ as a new and distinct Chrysanthemumplant:

-   -   1. Upright plant habit; vigorous growth habit.    -   2. Dark green-colored leaves.    -   3. Uniform and freely flowering habit.    -   4. Strong upright flowering stems with numerous inflorescences.    -   5. Single-type inflorescences with bright yellow-colored ray        florets and bright green-colored disc florets.    -   6. Relatively tolerant to high and low production temperatures.

Plants of the new Chrysanthemum differ from plants of the female parentselection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are not as freely flowering        as plants of the female parent selection.    -   2. Plants of the new Chrysanthemum are more high temperature        tolerant than plants of the female parent selection.

Plants of the new Chrysanthemum differ from plants of the male parentselection in the following characteristics:

-   -   1. Inflorescences of plants of the new Chrysanthemum are smaller        than inflorescences of plants of the male parent selection.    -   2. Disc florets of plants of the new Chrysanthemum are bright        green in color whereas disc florets of plants of the male parent        selection are light yellow in color.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘DLFCOP2’, not patented. In side-by-sidecomparisons plants of the new Chrysanthemum differ from plants of‘DLFCOP2’ in the following characteristics:

-   -   1. Ray florets of plants of the new Chrysanthemum are mostly        flat whereas ray florets of plants of ‘DLFCOP2’ are somewhat        convex.    -   2. Ray florets of plants of the new Chrysanthemum are slightly        darker yellow in color than ray florets of plants of ‘DLFCOP2’.

Plants of the new Chrysanthemum can also be compared to plants ofChrysanthemum X morifolium ‘Delilimonada’ not patented. In side-by-sidecomparisons plants of the new Chrysanthemum differ from plants of‘Delilimonada’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flower about four days later        than plants of ‘Delilimonada’.    -   2. Ray florets of plants of the new Chrysanthemum are darker        yellow in color than ray florets of plants of ‘Delilimonada’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Chrysanthemum plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photographs may differ slightly from the color valuescited in the detailed botanical description which accurately describethe colors of the new Chrysanthemum plant.

The photograph on the first sheet comprises a side perspective view of atypical flowering stem of ‘DLFVIBE2’ grown as a spray-type.

The photograph on the second sheet comprises close-up views of the lower(top of the photographic sheet) and upper surfaces (bottom of thephotographic sheet) of typical inflorescences and leaves of ‘DLFVIBE2’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the winter in ground beds in aglass-covered greenhouse in Maasdijk, The Netherlands and under culturalpractices typical of commercial cut Chrysanthemum production. Plantswere initially given long day/short night treatments followed by shortday/long night treatments to induce flower initiation and development.During the production of the plants, day temperatures ranged from 18° C.to 22° C., night temperatures ranged from 20° C. to 25° C. and lightlevels averaged 8 klux. Plants were grown as single-stem plants and wereten weeks old when the photographs and the description were taken. Inthe following description, color references are made to The RoyalHorticultural Society Colour Chart, 2015 Edition, except where generalterms of ordinary dictionary significance are used.
